INTRODUCTION
Lesions of the posterior parietal area in humansproduce interesting
spatial-perceptual and spatial-behavioral deficits. Amongthe moreimpor-
tant deficits observedare loss of spatial memories,problemsrepresenting
spatial relations in modelsor drawings, disturbances in the spatial dis-
tribution of attention, andthe inability to localize visual targets. Posterior
parietal lesions in nonhumanprimates also produce visual spatial deficits
not unlike those found in humans. Mountcastle and his colleagues were
the first to explore this area, using single cell recording techniques in
behaving monkeysover 13 years ago. Subsequent work by Mountcastle,
Lynchand colleagues, Hyvarinen and colleagues, Robinson, Goldberg &
Stanton, and Sakata and colleagues during the period of the late 1970s
